AT THE END of the 1980s, the decade of big spenders, the idea of a supercar was moving into a new dimension. The Jaguar XJ220, the McLaren F1 and Bugatti EB110 were in preparation and promised to bring race-car performance to the road. That raised the inevitable question: why not make a contemporary race car street-legal?
Take a Group C sports-racer, fit catalytic converters and silencers, change the engine control unit, add licence plates and (a few) creature comforts and you could have a spectacular road car. That was the thinking that led to the Schuppan-Porsches that flowered for a short time from 1991.
